of a device of the character indicated which is constructed and arranged in such manner as to effect a self cleaning operation in the sprinkler head.

Another object of the invention is the provision of a device of the character indicated which is constructed and arranged in such manner that many different variations of width, angle, coarseness and direction of spray may be efiected.

Another object of the invention is the provision of a device of the character indicated which may readily be adjusted to spray any size square or rectangular area.

Another object of the invention is the provision of a device of the character indicated which is readily adjustable so that the degree of reciprocation of the sprayer head may be changed to suit various operation conditions. v

Another object of the invention is the provision of reciprocable sprayer head which is constructed and arranged in such manner that the angle of reciprocation may be readily adjusted.

Another object of the invention is the provision of a device of the character indicated which is constructed and arranged in such manner that the internal water pressure is utilized to efiect a seal between the working parts.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawings, forming part of the width disclosure, in which drawings:

Fig. 13 is an end view of the device shown in Fig. 10 with the reciprocating mechanism on dead center.

Referring now more particularly to the drawthreaded fitting l3, adapted to accommcate the threaded terminal of a conventional garden hose. The base I2 is threaded as its other end, as at 14 (Fig. 2) and is adapted to support a tubular distributor member 15, the latter being threaded at each end, as at l6 and IT, to accommodate the end members I8 and H9. The end member I 8 has an inwardly extending shoulder 20, which is adapted to engage and hold in posi-; tion the flange 2f of the sprinkler head support 22, which is adapted to rotate on its l0ngitudinal axis as hereinafter described.

Threadedly mounted on the end of the support 22 is a sprinkler head 23, which is constructed and arranged as illustrated in Figs. 5. to 9 inclusive. The head 23 (Fig- 6) consists of a cylindrical member 24 having end closure members 25 and 26. each of which has a centrally disposed hub portion 21 and 28 bored to accommodate the adjusting screw 29, at one end of which is the knurled knob 30.

The end member 25 (Fig. 6) travels axially with the screw 29 by reason of the retainer 32' which engages the screw 29, as at 33.. The hub 28 of the end member 26 is threadeias at 34, to engage the threads of the screw 29. Washers seal the opening in the hub 21 to preventthe leakage of water around the screw 29.

The member 25 is provided with a plurality of slots throughwhich the water is discharged along the periphery of the head, and the member 24 is undercut, as at 31, to provide a passageway to the slots 36. The axial adjustment of the end member 25 with respect to the member 24 determines the coarseness of the spray.

The distributorr|5-.(Eigs. 1 and 2) is secured to an angle, plate;38 by extending the end I9 through an opening in the plate 38 and threading thereon the nut 39. The plate 38 also serves as a mounting for the fluid motor 40 which is secured thereto by screws 4|. The motor 40 may be of any reciprocating pistontype,,but in the embodiment herein disclosed ,I illustrate the use of a conventional Trico windshield wiper motor, having a rack 42 secured to the piston 43, and a pinion 44, fixed for rotation with-the spindle 45, which is provided with seals 46, and a'handle 41, which is secured in position by the nut 48. The pinion boXi49Hhas a .cover plate 50. The spindle ;is..pinned'to theupinion 44, as at 5|, and to a coupling 52, as at 53, which coupling 52,15,111. turn secured ,tothemember 22, by the tongue 54 and the slot 55, formed in the member 22.. Other =slotsjii.areiormed in the endof the member 22 to permit the entry of water from the watch inlet pipe 12.;

I provide an automatic seal between the parts 20- and.2I andnbetweenuthe parts52 and I5, by means of the water pressure onethe interior of the devices, The.in ternal.,water pressure .fcrces the. collar,5l oi .theucoupling .52 tightly against thegshoulder58 formed .on the member I5, and

it: also ,forces the. flange .21 of, ,the member 22 tightly againsttheshouldenn cf ,the end memb81f- 1| 8,. thus efiectingan automatic seal in opposite directions.

The motor. :40, has the conventional reversing valvemechanismfl, which, is connected to the distributor I5 by means of the small waterpipe 50,. .(Fig. 1) so, that water pressure from the distributor l5 is alternately. admitted tothe pistons,

at either end: of the .rack 42 Thevalve mechanism 59-isprovideduwith anairintake 6|.

In operatiom.it isvobviouspthat the sprinkler head 23.,will. rock from side toside, as the memberg22, thecoupling 52,,and the spindle,45 are actuated ,by the rack and pinion 44.

Inv Figs. .3 and 4 I illustrate amechanism similarH to, that shcwnin Figs. .1 and. 2, except thatj the pistons carrying the rack 42.are actuated by suction rather, than by direct water pressure from thedistributor. head I 5.

The suction iscreated, by inserting afittiug 62 in=-the waterinlet line .l2 next to the distributor l5. The fitting.",h'asiataperedpassageway 63 to which, connects..ai;transverse'=-bore 64, which 7 character. 66 (indicates a base to which is secured the water inlet 61, to the upper endorflwhich is secured. the. distributor. 68, to which is rockingly mounted. the ,sprinker ,head' 69,, which is similar to the head 23 already described. In this instance the motor 10 is..secured tothedistributor 68 by a-bracket I I The. spindle 5 12 whichyis rotated ,by the l rack l3 and pinionjgfl ps;,previously.described,; has:

connected.- to itat. "U3? shaped grocker, arm 15,

which engages a collar 18, through which extends a set screw 11. A second arm-I8 extends through the rear end of the set screw H, and through a stud 19 formed on the head 59, and is held in position by the wing nut 80. By adjusting the position of the collar 16 on the arms 15 and 18 different degrees of throwmay be effected, and when the collar 16 is; in the position shown in Fig. 13, the mechanism is on dead center and the head 69 will remain motionless. Thus it will be seen that I have disclosed another novel means for actuating the sprinkler head.

Having described my invention, what I claim and desire to secure by Letters Patent is:

spray distributing mechanism comprising a tubular-member threaded-at each end, apertured end members having threads in engagement with the threads of said tubular member, a tubular sprinkler head support rotatable inthe aperture of one of said endmembers, said support having an end flange adapted to engage an inwardly extending shoulder formedon said last-named end member, a rotatable couplingextending through the aperture of said other end member, said coupling iThe'structure defined in claim -1, in which said tubular support has a slot inoneend arranged tc engage a tongue formed on said coupling, whereby said tubular sprinkler head support and said; coupling may be rotated simultaneously about their longitudinal axes.
